To all whom it may concern.'

Be it known that l, SAMUEL CLYDE SWIN- DLER, a citizen ot' the United States7 residing at Pratt, in the county of Pratt and State of Kansas7 have invented certain new and useful Improvements in Combination Boilers and Stoves, of which the following is a specilication, reference being had to the accompanying drawings.

This invention relates to improvements in combination boilers and stoves and particularly to improvements in attachments by which the products of combustion from the stove are made to heat water for ordinary household or other purposes; and an object of this invention is to provide an attachment of the character just alluded to which will be simple in construction, comparatively cheap in manufacture and most eliicient in operation and which will utilize a largo percentage of the heat which would otherwise be wasted. lllhile the attachment may be used with the ordinary coal stove, it is particularly well adapted for use with gas, oil and vapor stoves.

In the drawings illustrating the principle of this invention and the best mode now known to me of applying that principle, Figure' l is a perspective view of the combination boiler (or water-heating attachment) and stove, parts being broken away and shown in section for the sake of clearness of illustration of the interior; and Fig. :2 is a vertical section of an attachment having two rows of holes for the reception of cooking utensils.

The stove a is provided with the usual legs b and burners c which are fed from a tank Z containing a suitable liquid fuel, such as gasolene, thc flow of the'tsame being controlled by the valves e. rihere is nothing new in the structure of the stove and, as above stated, any other suitable type of stove may be used in place of the one herein shown and described. The water-heating attachment or boiler is a substantially L- shaped receptacle having'a bottom wall g, end walls 7L, 2'., front walls y', 7c, a top wall m and a back wall n to which ishinged a lid or cover 0 designed to close the .opening p through which the boiler may be filled with water. lllthin the boiler f is'arranged an L-shaped tiue g, which is the main discharge iue and the upperA end of which is open and lies above the normal Water-level and below the lid o. ln the horizontal part .of the ue there is formed a vertical channel g which connects the water-space above the flue with the water-space below the same, the iiue being separated by suitable water-spaces from the back wall ln, bottom wall g, front Walls y', k, top wall m and end walls t, z'. The bottom wall g of the boiler f is formed with openings?1 from which extend the vertical tlues s the upper ends of which communicate with the horizontal part of the L-shaped iue o; and from the latter leads a pair of vertical tlues which are co-aXial with the vertical tlues e but are smaller in diameter than the same, whereby an overhang u is formed. The upper ends of the tlues t are formed with seats o for the lids w which close the openings a: in the top wall m. In the top of the front wall /lz and above the normal level of the water in the reservoir, there are.

the L-shaped flue (/v. ln the end wall t is tted a spigot or faucet e' by means of which water may be drawn from the reservoir f at will. The bottom ot' the latter may, as shown in the drawings, constitute the bottom of the stove; and around the front and ends of the bottom' wall (j a curved flange 3 extends and serves as a support for the lugs e in which the stems of the valves e are mounted.

The operation or' my new combined stove and boiler will be readily understood from the foregoing description taken in connection with the drawings and, briefly explained, is as follows: When it is desired to cook and to heat the water at the same time, 'the lid w is removed from each hole that is to be used for cooking; and the cooking utensil is placed therein or thereover, after which the burner o `elow the utensil or vessel is lighted.. It desired, the other burner or burners may also be lighted, the lids w above them being left in place. The products of combustion ioW up through the liues s and a part of them strikes the overhanging parts u of the top oi. the main iiue g and flow along the latter into the top of the tank f constituting the main or bodv part of the boiler f and escape therefrom.

removed, is reec-ted back and passes out Ais through the main flue g'and the discharge oriiices y. lThe top of the horizontal part f of the boiler f serves as a stove-top upon which the ordinary operations of cooking or culinary processes may be carried out or performed; and this part is, as clearly shown in the drawings, shallow as compared with the tank part f andserves as a waterjacket for 'the burners c, the walls of the tiues s, transmitting heat :from the hot 1gases to 4the water in the water-spaces surrounding them` The channel gf aids in maintaining the vcirculation of the water from the tank f tothe `water-space in the chambered hot-plate f. The water-supply in the tank f may be replenished by raising the cover o and pouring in the waterby the pailful, tor .exampe; during the ordinary operation of the apparatus, however,A thetop of the rnk f is kept closed. The

holes y will allow the steam formed in thetank to escape with the wastel gases.

. l claim: A

l. A structure of the character described, comprising a tank for holding water; a chambered hot-plate which projects laterally from the tank and which is formed with a water-space that communicates with the water-space in the tank, said hot-plate having an opening in its top and an aperture in its bottom below said opening for the ingress ot' the'products of combustion; a substantially upright flue which is arranged within-the water-space of the hot-plate and the bottom of which ovenlies said aperture and the top of which lies closely adjacent to the wall of said opening and is adapted to receive the bottom of a cooking utensil; and a main discharge Hue which is provided with a water-circulation channel and is arranged in the water-spaces of the hot-plate and of the tank and is bathed by the Iwater' in said water-spaces and which communicates 'with said upright flue and leads laterally therefrom into the tank. v

2. A structure of the character described, comprising a tank for holding Water; a chambered hot-plate which projects laterally frein the tank and which is formed with a Water-space that communicates with the Loaaeea Water-space in the tank, said hot-plate having an opening in its top and an a )crture in its bottom below said openingsy or the ingress of the products of combustion; a flue the lower end of which lies closely adjacent to the wall oit said aperture and `which is arranged within the water-space of the hot-plate; second flue the upper end of which lies closely adjacent to the wall of said opening and. is adapted to receive the bottom of a cooking utensil and the lower end of which is opposed to the upper end ofthe other lue and which 1s arranged within the water-space of the'hotplate; and a main dischargeI line which is provided with a water-circulation channel and is arranged in the water-spaces of the hot-plate and of the tank and is bathed by the water in said water-spaces and which communicates'with'both'said flues and leads laterally therefrom into the tank; one ofthe last-named tiuesbeing wider than the other.

3. A structure of the character described, comprising a normally-closed tank which is adapted to holdwater and is formed with an air space above the normal water-level in the tank land with vents from 'said air space; a chambered hot-plate vwhich projects laterally from the tank and which is formed with a water-space that communicates with the water-space in the tank, said hot-plate having an opening in its top and an aperture in its bottom below said opening for the ingress of the products Ofcombustion; a substantially upright iiue which is arranged within the water-space of the,

hot-plate and the bottom of which lies closely adjacent to the wall of the said opening and is adapted to receive the bottom of a cooking utensil; and a main discharge flue which communicates with said upright flue and lease laterally therefrom into the tank and the open upper end of which is arranged to discharge products of combustion into the air-space above the normal water-level in the tank.
